Welcome to March. The Madness is officially here, and we're celebrating the occasion by looking back at some of the most incredible Hail Mary plays in the history of the men's NCAA Tournament.

The Madness started early last year. Alabama State won the opening game of the First Four in dramatic fashion. Tied at 68 with 3.4 seconds left, Micah Simpson launched an 85-foot Hail Mary pass that tipped off multiple players before landing in the hands of Knox, who was all alone for a game-winning layup.

With 3.3 seconds remaining in the Final Four, Suggs took an inbound pass, used three dribbles, and banked home a 37-footer from just past midcourt to send Gonzaga to the title game. Suggs' celebration - jumping up on a table on press row - is as memorable as the shot itself.

Northern Iowa's Jesperson drilled four 3-pointers in a first-round upset win over the Longhorns, but none were as memorable (or unlikely) as his half-court heave that banked in as time expired to give the Panthers a 75-72 win. According to the NCAA, Jesperson's 50-foot shot is the longest game-winning buzzer-beater in March Madness history.

Laettner's turnaround buzzer-beater with 0.3 seconds left in the 1992 Elite Eight is arguably the most famous shot in tourney history. But the iconic moment wouldn't have been possible without Grant Hill heaving a prayer on the inbound pass from under his own basket that found Laettner at the free-throw line. Duke went on to win the national championship.
